(Updates to midday)
HONG KONG, July 27 (Reuters) - Hong Kong and China shares rose on Monday in a liquidity bounce as investors continued to bet on a speedy recovery in the Chinese economy, while the Shanghai exchange's first new listing in nearly a year made an impressive debut.
China's Sichuan Expressway soared 175 percent from its IPO price in its market debut to 9.89 yuan, triggering a suspension of trade. The shares were buoyed by the company's strong growth prospects and a relatively low IPO price, although analysts warned of excessive speculation in the stock.
The stock rose 3.5 percent to HK$3.53 in Hong Kong.
Local-currency A shares in the toll road operator kicked off trading at 7.60 yuan, up from the IPO price of 3.60 yuan, giving its A shares a dramatic 153 percent premium over the HK$3.41 closing price for its Hong Kong-listed H shares on Friday.
Here are the index moves and top stock moves by midday-
HONG KONG
* The benchmark Hang Seng Index was up 1.3 percent at 20,246.22 with shares worth HK$45.5 billion changing hands.
The index rose to 20,385.69 earlier in the session, its highest level since September 9 last year.
* Property stocks surged, with home sales and prices continuing to climb as demand picks up pace in the low interest rate environment while supply remains tight. Conglomerate New World Development advanced 4.6 percent while Henderson Land was up 4.1 percent.
"Hong Kong's main difference from any other property market in the world is its very low supply. This sets the base for a very strong rebound as the economy rebounds and liquidity seeps back into the system," said Eric Wong, analyst with UBS.
UBS raised its property price forecasts across the board, estimating a 32 percent increase in home prices between June 2009 to December 2010.
* The China Enterprises Index, which represents top locally listed mainland Chinese stocks, was 1.7 percent higher at 12,189.56.
* China Shenhua Energy extended Friday's gains to pile on 5.7 percent following strong power output data last week, which bodes well for coal demand.
China's power output in mid-July via major grids rose 7.9 percent on year, lifted by hotter-than-usual weather and a revival in demand on a continued economic rebound, the official Shanghai Securities News reported on Friday.
Power plant equipment maker Harbin Power rose 5.6 percent while Shanghai Electric jumped 3.6 percent.
* Macau's casino stocks gained on Monday after the gambling haven chose a new chief executive over the weekend, with no chnages expected to gaming policy.
Galaxy Entertainment rose 2.2 percent, while casino tycoon Stanley Ho's SJM Holdings tacked on 1.6 percent.
* Aluminum Corp of China (Chalco) reversed course, from early step losses, to gain 3.2 percent as investors shrugged off a warning from the world's No.3 alumina producer of a loss in the first half of 2009 on low aluminum demand and prices.
Analysts said much of the bad news had been factored into Chalco's share price after its dramatic plunge last year. The stock, which fell 74 percent last year, has clawed back 127 percent so far in 2009. The stock rose to HK$9.35 by mid-morning after dropping to HK$8.49 earlier.
